Sites set with Multisite Privacy settings not showing up with Buddypress


We have set up buddypress on the main site and users have their own blog.

We have set the mulitsite privacy settings to: Only allow logged in users to see all sites.
Allow override: no.

On the buddypress site-directory-page however the sites do not show up (unless you are a superadmin). We want other users to be able to see the sites as well.

If we manually change the visibility setting on a single site to "Allow search engines to index this site" this site does show up in the site-directory-page.

Any help would be appreciated.

Thanks in advance.
